Filed: 1989-12-13
Abstract: PURPOSE: To obtain the highest density under the sintered condition in several times sintering by using conventional equipment and method, by conducting heating to a sintering temperature, sintering and cooling under particular conditions and under protective gas. CONSTITUTION: A formed and compressed artificial tooth is placed, for example, in a graphite box after having been dried in the air (for 5-25 minutes), and is subjected to heat treatment for 5-45 minutes in the temperature range of 100-400 deg.C. Then, it is heated up to 800 deg.C with the average temperature increase of 50-300K/min, and heated from the preheating temperature to sintering temperature T with the average temperature increase of 20-200K/min by using the air or under protective gas. In this case, sintering temperature T is between the T solidus-200 deg.C and T solidus-70 deg.C, and the T solidus is a solidus temperature of a sintered alloy. Under this temperature, the tooth is sintered for 5-45 minutes by using the air or under protective gas, and cooled in the temperature range lower than 900 deg.C under the vacuum of 1-50HPa or under protective gas. In particular, under the vacuum cooling, such sufficiently high density that pairs the porosity of independent pores can be achieved even after several times sintering.

A quadri-partite image consisting of the image elements of an odd numbered row-odd numbered column, an odd numbered row-even numbered column, an even numbered row-even numbered column and an even numbered row-odd numbered column within the image elements of the precision image is constituted. The division images are divided into the odd numbered column image elements and the even numbered column image elements.  The average image element of the image elements being adjacent in the horizontal direction is generated and interpolated(*A-*D) in the space area of the even numbered column in the division image consisting of the odd numbered column image elements and the space area of the odd numbered column in the division image consisting of the even numbered column image elements. The interpolated division images are obtained(A-D). Image data expressing the division image is DCT compressed at every DCT block and recorded in a magnetic tape. Since the high frequency components are a few so that the high frequency components is prevented from being cut off even with DCT compression and noise is also prevented from occurring in a reproduction image.
